In the literature (EP-A 223 406, EP-A 249 708, EP-A 287 072 and EP-A 287 079) describes herbicidal substituted salicylic acids and their sulfur analogs. However, their action is unsatisfactory.

It is an object of the present invention to provide novel salicylic acid derivatives or their sulfur analogs having improved herbicidal properties and possessing plant growth-regulating properties.

We have found that this object is achieved by the compounds of the formula I, defined at the outset. We have also found processes for the preparation of the compounds I and methods for controlling undesirable plant growth using the compounds I. We have furthermore found that salicylic acid derivatives of the general formula I defined above have excellent plant growth-regulating properties. The novel salicylic acid derivatives II' have been found as intermediates for the preparation of the compounds I.

Compounds of the formula I are obtained, for example, by reacting an appropriately substituted salicylic acid derivative of the formula II, which in specific cases is known or can be prepared by conventional methods starting from known intermediates, with an appropriate compound of the formula III in the presence of a base. ##STR6##

In formula III, R¹³ is a conventional nucleofugic leaving group, for example halogen, such as chlorine, bromine or iodine, aryl- or alkylsulfonyl, such as toluenesulfonyl or methylsulfonyl, or another equivalent leaving group. Compounds of the formula III having a reactive substituent R¹³ are known or are readily obtainable on the basis of the general technical knowledge. Suitable bases are alkali metal or alkaline earth metal hydrides, such as NaH or CaH₂, alkali metal hydroxides, such as NaOH and KOH, alkali metal alcoholates, such as potassium tert-butylate, alkali metal carbonates, such as Na₂ CO₃ and K₂ CO₃, alkali metal amides, such as NaNH₂ and lithium diisopropylamide, or tertiary amines. When an inorganic base is used, a phase transfer catalyst may be added if it promotes conversion.

Where the compounds of the formula I prepared in the manner described are carboxylic acids (i.e. when R¹ is hydroxyl), they can also be converted into other compounds described, for example by first converting the carboxylic acid in a conventional manner into an activated form, such as a halide or imidazolide, and then reacting this with the corresponding hydroxy compound. These two steps can also be simplified, for example, by allowing the carboxylic acid to act on the hydroxy compound in the presence of a water-eliminating agent, such as a carbodiimide.

When X is oxygen and A is a heteroaromatic or aromatic radical bonded via a carbon atom, the intermediates of the formula II can be synthesized according to the scheme below, from a 1,3-dicarbonyl compound IV (where R⁵ is unsubstituted or phenyl-substituted C₁ -C₁₀ -alkyl, in particular C₁ -C₄ -alkyl) and an α,β-unsaturated ketone V: ##STR7##

Alternatively, the intermediates of the formula II' can also be prepared according to the scheme below, from a methylenephosphorane IV' and an α,β-unsaturated ketone V: ##STR8##

The compounds IV, IV' and V are generally known or can readily be prepared by conventional processes. Suitable bases are the abovementioned compounds. Suitable acids are strong acids, for example hydrochloric acid, hydrobromic acid, tetrafluoboric acid, toluenesulfonic acid or trifluoroacetic acid. Elimination of hydrogen bromide can be carried out thermally or in the presence of a base, for example an organic amine.

If, in formula II, A is a heteroaromatic radical bonded via a nitrogen atom and X is oxygen, this intermediate can be synthesized according to the following scheme: ##STR9##

M+A-is the particular alkali metal azolide. Suitable alcohols for the cleavage of the nitrile VII in variant a) are, in particular, C₁ -C₄ -alkyl alcohols.

The intermediates of the formula II which are prepared as described above are usually obtained as alkyl esters. These can be hydrolyzed by the known methods to give the carboxylic acids. The latter can then be converted by conventional methods into various esters, which are required for the preparation of active ingredients of the formula I as claimed in claim 1.

Alternatively, the intermediates of the formula VII can also be reacted by generally known methods with alkali metal or tetraalkylammonium hydroxides to give the corresponding amides, and then with mineral acids, for example concentrated hydrochloric acid, to give the carboxylic acids, and then with concentrated hydrobromic acid to form the salicylic acids IIb. These steps can, if required, be carried out without isolating the intermediates.

The herbicidal and growth-regulating agents, I, or agents containing them, may be applied for instance in the form of directly sprayable solutions, powders, suspensions, (including high-percentage aqueous, oily or other suspensions), dispersions, emulsions, oil dispersion, pastes, dusts, broadcasting agents, or granules by spraying, atomizing, dusting, broadcasting or watering. The forms of application depend entirely on the purpose for which the agents are being used, but they must ensure as fine a distribution of the active ingredients according to the invention as possible.

The formulations contain from 0.1 to 95, and preferably 0.5 to 90, % by weight of active ingredient. The active ingredients are employed in a purity of 90 to 100, and preferably 95 to 100, % (according to the NMR spectrum).

Examples of formulations are as follows:

I. 90 parts by weight of compound no. 1.004 is mixed with 10 parts by weight of N-methyl-alpha-pyrrolidone. A mixture is obtained which is suitable for application in the form of very fine drops.

II. 20 parts by weight of compound no. 1.005 is dissolved in a mixture consisting of 90 parts by weight of xylene, 10 parts by weight of the adduct of 8 to 10 moles of ethylene oxide and 1 mole of oleic acid-N-monoethanolamide, 5 parts by weight of the calcium salt of dodecylbenzenesulfonic acid, and 5 parts by weight of the adduct of 40 moles of ethylene oxide and 1 mole of castor oil.

A stable oily dispersion is obtained.

The active ingredients or the herbicidal agents containing them may be applied pre- or postemergence. If certain crop plants tolerate the active ingredients less well, application techniques may be used in which the herbicidal agents are sprayed from suitable equipment in such a manner that the leaves of sensitive crop plants are if possible not touched, and the agents reach the soil or the unwanted plants growing beneath the crop plants (post-directed, lay-by treatment).

The application rates depend on the objective to be achieved, the time of the year, the plants to be combated and their growth stage, and are from 0.001 to 3.0, preferably 0.005 to 0.5, kg of active ingredient per hectare.

The growth-regulating salicylic acid derivatives of the formula I may exercise of variety of influences on practically all plant development stages, and are therefore used as growth regulators. The diversity of action of growth regulators depends especially on

A) the type and variety of plant;

b) the time applied, with reference to the development stage of the plants and the time of the year;

c) the place and method of application (seed treatment, soil treatment, or application to foliage);

d) climatic factors, e.g., average temperature, amount of precipitation, sunshine and duration;

e) soil conditions (including fertilization);

f) the formulation of the active ingredient; and

g) the concentration at which the active ingredient is applied.

A description of some of the various possibilities of using the growth regulators according to the invention in agriculture and horticulture is given below.

A. Vegetative plant growth can be inhibited to a considerable extent, a fact which is manifested particularly in a reduction in plant height. The treated plants thus have a compact habit; furthermore, the leaf color is darker.

Of advantage in practice is for example the reduction in grass growth on roadsides, hedges, canal embankments and on areas such as parks, sportsgrounds, fruit orchards, lawns and airfields, thus reducing expensive and time-consuming mowing.

A further feature of economic interest is the increase in the rigor of crops which tend to lodge, such as cereals, Indian corn, sunflowers and soybeans. The shortening and strengthening of the stem thus caused reduces or eliminates the danger of lodging under unfavorable weather conditions.

The use of growth regulators is also important for inhibiting plant height and changing the time of ripening in cotton. It is thus possible for this important crop to be harvested completely mechanically.

In fruit and other trees, pruning costs can be reduced with growth regulators. With growth regulators, it is also possible to break up the alternate breeding rhythm of fruit trees.

Growth regulators may also increase or inhibit lateral branching. This is of interest when, for instance in tobacco plants, it is desired to inhibit the formation of lateral shoots (suckers) in favor of leaf development.

With growth regulators, it is possible for instance in winter rape to considerably increase the resistance to freeze injury. On the one hand, upward growth and the development of a too luxuriant (and thus particularly frost-susceptible) leaf or plant mass are inhibited; on the other, the young rape plants are kept, in spite of favorable growth conditions, in the vegetative development stage before winter frosts begin. The danger of freeze injury is thus eliminated in plants which tend to lose prematurely their inhibition to bloom and pass into the generative phase. In other crops, too, e.g., winter cereals, it is advantageous if the plants are well tillered in the fall as a result of treatment with the compounds according to the invention, but enter winter with not too lush a growth. This is a preventive measure against increased susceptibility to freeze injury and--because of the relatively low leaf or plant mass--attack by various (especially fungus) diseases. The inhibition of vegetative growth also makes closer planting possible in numerous crops, which means an increase in yield, based on the area cropped.

B. Better yields both of plant parts and plant materials may be obtained with the novel agents. It is thus for instance possible to induce increased formation of buds, blossom, leaves, fruit, seed grains, roots and tubers, to increase the sugar content of sugarbeets, sugarcane and citrus fruit, to raise the protein content of cereals and soybeans, and to stimulate the increased formation of latex in rubber trees.

The salicylic acid derivatives of the formula I may raise the yield by influencing plant metabolism or by promoting or inhibiting vegetative and/or generative plant growth.

C. It is also possible with growth regulators to shorten or lengthen growth stages and to accelerate or retard the ripening process in plant parts either before or after harvesting.

A factor of economic interest is for example the facilitation of harvesting made possible by a chemical, temporally concentrated loosening (abscission) of the adherence of stalks to the branches of citrus fruit, olive trees, and other kinds of pomes, drupes and indehiscent fruit. The same mechanism, i.e., promotion of the formation of separation layers between fruit or leaf and stem of the plant, is also essential for a readily controllable defoliation of crop plants, e.g., cotton.

Further, transpiration in crop plants may be reduced with growth regulators. This is particularly important for plants growing in agricultural areas which are expensive to irrigate, e.g, in arid or semi-arid areas. Irrigation frequency can be reduced by using the compounds according to the invention, making for lower costs. As a result of the use of growth regulators, the water available can be better utilized, because, inter alia,

the size of the stomata opening is reduced;

a thicker epidermis and cuticle are formed;

penetration of the soil by the roots is improved;

the micro-climate in the stand is favorably influenced by the more compact growth.

The active ingredients according to the invention may be applied not only to the seed (as a dressing), but also to the soil, i.e., via the roots, and to the foliage by spraying.

As a result of the good tolerance by crop plants, the application rate when the active ingredients are used as growth regulators may vary within wide limits.

When the active ingredients are used for treating seed, amounts of from 0.001 to 50, and preferably from 0.01 to 10, g per kg of seed are generally required. For foliage and soil treatment, amounts of from 0.001 to 10, preferably from 0.01 to 3, and especially from 0.01 to 0.5, kg/ha are generally considered to be sufficient.

The active ingredients or the herbicidal agents containing them may be applied pre- or postemergence. If certain crop plants tolerate the active ingredients less well, application techniques may be used in which the herbicidal agents are sprayed from suitable equipment in such a manner that the leaves of sensitive crop plants are if possible not touched, and the agents reach the soil or the unwanted plants growing beneath the crop plants (post-directed, lay-by treatment).

The application rates depend on the objective to be achieved, the time of the year, the plants to be combated and their growth stage, and are from 0.001 to 3.0, preferably 0.01 to 1.0, kg of active ingredient per hectare.

SYNTHESIS EXAMPLES

The methods described in the Synthesis Examples below were used, with appropriate modification of the starting compounds, to obtain further compounds I. The compounds thus obtained are listed in the Tables below, together with physical data. Compounds without this data can be synthesized similarly from the corresponding starting compounds. The structures shown in the Table describe particularly preferred active ingredients of the formula I.

EXAMPLE 1 Methyl 3-(4,6-dimethoxypyrimidin-2-yl)-oxybiphenyl-2-carboxylate (compound No. 1005): a) Methyl 6-phenylsalicylate: Variant 1

58 g (0.5 mol) of methyl acetoacetate are added to a solution of 0.5 g of sodium hydride in 100 ml of dry ethanol, 66 g (0.5 mol) of cinnamaldehyde are rapidly added dropwise and the mixture is stirred for about 10 h at room temperature. The mixture is then saturated at 0° C. with dry HCl gas and then stirred for a further 1 day at room temperature (20° C.). The solvent is removed and the remaining residue is distilled under reduced pressure, HCl gas initially being liberated. Fractions passing over from 115° to 165° C./0.2 mbar are combined and are chromatographed over silica gel (elution with toluene/cyclohexane). 33.7 g of a yellow oil are obtained as an intermediate. This is dissolved in 150 ml of methylene chloride, and a solution of 22.9 g (0.14 mol) of bromine in 150 ml of glacial acetic acid is added rapidly at 0° C., and the mixture is slowly heated up and is refluxed for one hour. The reaction solution is poured into 200 ml of methylene chloride and 500 ml of water. The organic phase is separated off and worked up in a conventional manner. A yellow solid is obtained as an intermediate, which is dissolved in 400 ml of methyl tert-butyl ether for further processing. 55 g (0.56 mol) of triethylamine are added and the mixture is refluxed for 5 h. Thereafter, 300 ml of water are added, and the organic phase is separated off and worked up in a conventional manner. The residue is distilled at 100°-114° C./0.2 mbar. Yield: 11.9 g.

At this temperature, 20 g (0.15 mol) of cinnamaldehyde are added a little at a time, followed by 5-10 drops of water, and the initially exothermic reaction requires cooling. The reaction is continued at 35° C. until the ylide has been completely converted (TLC check, about 12-14 h. The reaction mixture is then rendered acidic with 10% strength hydrochloric acid and, after the addition of 1 l of water, is extracted with four times 150 ml of ether. The combined ether phases are extracted by shaking in 200 ml of water and 200 ml of saturated sodium chloride solution, dried over sodium sulfate and evaporated down. The remaining blackish brown residue is taken up in 400 ml of methyl tert-butyl ether and boiled for several hours. After cooling, it is filtered off from the insoluble residue (triphenylphosphine oxide), and the filtrate is evaporated down. The remaining oil is purified by chromatography over silica gel (mobile phase: toluene/ethyl acetate with gradually increasing ethyl acetate content . All fractions before the triphenylphosphine oxide are combined and are brominated, aromatized and worked up similarly to the above method. 14.5 g of product are obtained.

11.4 g (0.05 mol) of methyl 3-hydroxybiphenyl-2-carboxylate in 50 ml of dry dimethylformamide are initially taken, and 1.5 g (0.05 mol) of 80% strength sodium hydride are added a little at a time at from 0° to 5° C., while stirring. 10.9 g (0.05 mol) of 4,6-dimethoxy-2-methylsulfonylpyrimidine are then added at room temperature, the mixture is heated to 90° C. and stirring is continued at this temperature for 6 h. The solution thus obtained is poured into water. The mixture is extracted with methylene chloride and the extract is washed with water, dried over sodium sulfate and evaporated down. The crude product can be further purified by column chromatography using toluene/ethyl acetate, with the result that 9.6 g of a solid of melting point 98°-102° C. is obtained.

Examples demonstrating herbicidal action

The herbicidal action of the salicylic acid derivatives of the formula I is demonstrated in greenhouse experiments.

The vessels employed were plastic flowerpots having a volume of 300 cm³ and filled with a sandy loam containing about 3.0% humus. The seeds of the test plants were sown separately, according to species.

For the preemergence treatment, the formulated active ingredients were applied to the surface of the soil immediately after the seeds had been sown. The compounds were emulsified or suspended in water as vehicle, and sprayed through finely distributing nozzles. After the agents had been applied, the vessels were lightly sprinkler-irrigated to induce germination and growth. Transparent plastic covers were then placed on the vessels until the plants had taken root. The cover ensured uniform germination of the plants, insofar as this was not impaired by the active ingredients.

For the postemergence treatment, the plants were grown, depending on growth form, to a height of 3 to 15 cm before being treated with the compounds, suspended or emulsified in water. The plants were either sown and gown in the same vessels, or they were grown separately as seedlings and transplanted to the test vessels a few days before treatment. The application rate for postemergence treatment was 0.5 kg/ha.

The pots were set up in the greenhouse, heat-loving species at 20° to 35° C., and species from moderate climates at 10° to 25° C. The experiments were run for from 2 to 4 weeks. During this period the plants were tended and their reactions to the various treatments assessed. The assessment scale was 0 to 100, 100 denoting nonemergence or complete destruction of at least the visible plant parts, and 0 denoting no damage or normal growth.

The plants employed for the experiments were Bromus inermis, Echinochloa crus-galli and Ipomoea spp.

Compound 1.004, applied postemergence at a rate of 0.5 kg/ha, provided excellent control of unwanted plants.
